Definitions
- an object of the present invention is to provide a silver nanoink having a significantly improved silver concentration while maintaining good dispersibility of silver nanoparticles.
- Silver fines that are / 0 are provided.
- the organic protective material an amine compound having a molecular weight of 100 to 100 is preferably used, and a substance having one or more unsaturated bonds in one molecule is particularly suitable.
- This fine silver powder has a crystallite diameter of, for example, 20 nm or less in the (1 1 1) crystal plane of silver.
- the present invention also provides an ink in which the silver fine powder particles are dispersed in an organic solvent at a silver concentration of 10% by mass or more and have a viscosity of 50 mPa ⁇ s or less.
- FIG. 1 is a diagram schematically showing a heat pattern by a TG—DTA apparatus employed for measuring the ratio of an organic protective material.
- the inventors have developed a silver fine powder in which silver nanoparticles are covered with an organic protective material as a silver fine powder exhibiting extremely good dispersibility in an organic solvent.
- an organic protective material as a silver fine powder exhibiting extremely good dispersibility in an organic solvent.
- the reducing agent a solvent alcohol or polyol is used. This makes it possible to obtain silver nanoparticles with little impurity contamination. In the reaction, it is efficient to perform a reflux operation. For this reason, it is preferable that the boiling point of the alcohol or polyol is low. Specifically, the boiling point is preferably 300 ° C. or lower, preferably 20 ° C. or lower, and more preferably 150 ° C. or lower. In addition, it is preferable from the viewpoint of reducing ability that the alcohol has as long a carbon chain as possible.
